摘要： An overload protective device to be disposed in an electric circuit serving to supply current to a load has a pair of fixed contacts (7,8) provided inside of a case (19 and an inversible disk-like bimetal (5) of a curved shape having a pair of movable contacts (3,4) capable of coming in contact with the fixed contacts, respectively. A shaft (6) is fixed to the case at one end thereof and formed with a head portion (6a) at the free end portion. The shaft extends though a hole formed in the central portion of the bimetal. When the bimetal breaks, circuit breaking means (19) separate the contacts permanent to thereby prevent the load and the overload protective device from being burnt out.

摘要： PROBLEM TO BE SOLVED: To solve the problem of the conventional rolling piston compressor that a boundary portion between a vane of a piston and a roller is increased in stress during operation to cause breakage, and after finishing the vane, a stepped part from a not yet machined part is produced in the vicinity of the boundary portion between the vane and the roller, resulting in an increase in stress of the stepped part during operation to cause breakage. SOLUTION: A radius of curvature of a boundary portion between the vane of the piston and the roller of the rolling piston compressor is enlarged, and a circular arc of the boundary portion between the vane part and the roller part is arranged to intersect the straight line of the vane part and a circular arc of the outer periphery of the roller part.

摘要： PROBLEM TO BE SOLVED: To use magnetic flux on the stator side as effectively as possible, by preventing the magnetic flux from short-circuiting between adjacent different poles the magnetic flux of which is generated from permanent magnets different in polarity which are included in a rotor core of a permanent magnet type synchronous motor having different polarities. SOLUTION: A cavity 20 or a member of low magnetic permeability is inserted in a barrier 13 between permanent magnets 12 different in polarity which are included in a permanent magnet type synchronous motor, and an armature is constituted. Thereby the short-circuit of a magnetic flux between adjacent magnets is prevented, and the generated magnetic flux can be used effectively.

摘要： PURPOSE:To suppress a sliding loss and a leakage at the seal surface effectively, by forming the width of the seal surfaces of tip seals installed to the scroll laps of scroll members making larger gradually from the periphery to the center at the parts other than the center the end of the periphery. CONSTITUTION:Tip seals 7 and 8 are installed to the scroll laps 3b and 2b of the scroll members, in a fluid machine in which a pump having a compression space partitioned by engaging each other the first and the second scroll members which consist of end plates and scroll laps erected to the end plates, is driven by a driving member. The width of the seal surfaces 7a and 8a of the tip seals 7 and 8 is reduced as coming from the center to the periphery, and the width of groove inserting parts 7q and 8q are also reduced from the center to the periphery. On the other hand, the width of the scroll laps 2b and 3b is increased from the center to the periphery. Consequently, an excellent seal property is secured while suppressing the sliding loss at the sealing surface.

摘要： PURPOSE:To secure the desired pressure constantly and improve sealing performance and compression performance by opening one end of a seal or its mounting groove to a part where a contact part is fitted/removed to/from at the compression end time in the side face contact part of a lap isolating a discharge space from a compression chamber. CONSTITUTION:A scroll fluid machine is constituted of a pump part forming a compression chamber by engaging plural scroll members with each other, and a driving part for turning one scroll member without autorotation. A tip seal 7 with a sliding face 7a, and its mounting groove 3e are disposed at least at one scroll lap 3b. The scroll starting part of the tip seal 7 is opened to the side face of the lap 3b in such a way as to include a discharge space boundary part 3x which is a contact part fitted/removed at the time of a compression chamber being communicated with a discharge space upon terminating the compression stroke. The gap of the lap 3b, one of leakage passages, is thereby shut off by the seal 7 so as to secure a desired pressure ratio at all times.

摘要： PURPOSE:To cut off an electric current route speedily and permanently at a prescribed operational temperature and maintain high reliability in the case of normal use by arranging a thermally reactive curved disk shape member between a bimetal having movable contact points and a shaft head part. CONSTITUTION:A curved bimetal 5 protruding in the upper direction under its original condition is installed on a shaft 6 and a curved bimetal 19 protruding in-the lower direction is also installed on the shaft 6 between this bimetal 5 and the head part 6a of the shaft 6. When a temperature in a case 1 reaches a reversal operation temperature of the bimetal 19, at that moment, the bimetal 19 is put in a reversal movement in the reverse direction against the curving direction so far. Thereby, energizing force generated by the bimetal 19 against the bimetal 5 becomes smaller than energizing force generated by a spring 13 so that the bimetal 5 is hoisted. Thereby, movable contact points 3 and 4 are put under a separated condition from fixed contact points 7 and 8 so that an electric current route is put under a cut off condition.
